Subject: [PATCH v4 01/11] pwm: print error messages with pr_err() instead of pr_debug()
Date: Thu,  5 Jan 2017 00:36:44 +0100	[thread overview]
Message-ID: <1483573014-13185-2-git-send-email-lukma@denx.de> (raw)
In-Reply-To: <1483573014-13185-1-git-send-email-lukma@denx.de>

From: Lothar Wassmann <LW@KARO-electronics.de>

Make the messages that are printed in case of fatal errors actually
visible to the user without having to recompile the driver with
debugging enabled.
